FEBRUARY 1922
PURDUE UNIVERSITY AGRICULTURAL EXPERIMENT STATION LAFAYETTE, INDIANA
Nineteen Noxious Weeds of Indiana
A pasture infested with many varieties of weeds
Description, Eradication and Control of the Nineteen Weeds Designated as Noxious in the Indiana Seed Law
Albert A. Hansen
The history of agriculture is a record of man's attempt to successfully cope with the weed problem. When man selected certain plants to grow, he found a multitude of invading plants competing with his crops for moisture, food, sunlight and space. Recent experimental work indicates strongly that after the preparation of the seed bed. the principal object of cultivation is to prevent the growth of weeds. If this is true, then the eradication and control of weeds is one of the important problems confronting the farmer.
